Abstract: PURPOSE:To selectively take out the origin signal of an H or L level by providing a reference voltage generating means generating a plurality of reference voltages and a change-over means for selecting one of said reference voltages to supply the same to a comparator. CONSTITUTION:When an origin signal S2 of an H-level is required, a switch 3 is changed over toward a terminal 3b and voltage V1 is supplied to the reference voltage of a comparator 2. During a period when the origin is not detected by a sensor 1, voltage V0 is supplied to the comparator 2 from the sensor 1 and, during a period when said voltage V0 is equal to or less than the voltage V1, the output of the comparator 2 becomes an L-level. When the sensor 1 detects the origin, an electric signal S1 is outputted and, when the voltage V0 becomes the voltage V1, the output of the comparator 2 becomes an H-level. When the signal S1 exceeds the peak of the half cycle of the first half and the voltage V0 again becomes equal to the voltage V1, the output of the comparator 2 again returns to an L-level. When an origin signal S2 of an L-level is required, the switch 3 is changed over toward a terminal 3c and voltage V2 is supplied to the reference voltage of the comparator 2.
